This chapter evaluates how SO3, CO2, SO2, and O2 concentrations in feed gas, catalyst bed pressure, and catalyst bed input gas temperature affect maximum catalytic SO2 oxidation efficiency. 280 = (.4)^2 / (2x)^2 x and came up with x =.052 for the equilibrium concentration of O2 and.104 for the concentration of the SO2. 8.23 x 1084. If the given concentrations of the three gases are mixed, predict in which direction the net reaction will proceed toward equilibrium. At equilibrium SO3 is the predominant substance. The gases SO2, O2 and SO3 are allowed to reach equilibrium at a constant temperature.
